Abstract :
Niche technology was introduced in mind evolutionary computation to classify populations, reduce repetitive search and maintain population diversity as well as improve searching efficiency. Based on parameter optimization and tuning for the main steam temperature cascade control systems in power plants with serious parameter uncertainty, multi-disturbance and large delay, the simulation results show that the niche-based mind evolutionary algorithm has the advantages of fast optimization and low computational complexity; it is very effective for PID parameter optimization and endues main steam temperature control systems with better control qualities and better system robustness.
